9 different names are put into a computer and one of the names is Kevin. a) On Saturday, the computer chooses 2 names at random. The computer is set so that the same name can be chosen twice. What is the probability that Kevin is chosen at least once?
b) On Sunday the computer is set so that the same name cannot be chosen twice. Work out the probability that Kevin is chosen.

b) On Sunday the computer is set so that the same name cannot be chosen twice. Work out the probability that Kevin is chosen.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

exactly you go it
